Fram2 Mission With Amateur Radio Payload Scheduled to Launch March 31st
Fram2 is currently scheduled to launch on April 1, 2025 at 01:46:50 UTC (March 31, 2025 at 21:46:50 EDT).
The Fram2 mission is set to become the first human space flight in polar orbit – flying over the North and South poles. Named after the famous polar exploration ship Fram, which completed voyages to both the Arctic and Antarctica, we want to showcase pioneering spirit, wonder and technological innovation through the ages. The SpaceX Falcon 9 rocket will launch four astronauts from Europe and Australia into orbit for 3-5 days, target. On board the Dragon spacecraft are mission commander Chun Wang of Malta, vehicle commander Jannicke Mikkelsen of Norway, pilot Rabea Rogge of Germany and mission specialist Eric Philips of Australia. During the Fram2 mission Rabea Rogge, LB9NJ (Norway) and KD3AID (USA), will be operating the onboard amateur (ham) radio system sending SSTV images as part of a high school and university student competition. These SSTV images will also be available to be received by the general public during the mission. Read more about Fram2 and its crew here: f2.com
SSTV transmissions will be transmitted on 437.550 MHz FM using Robot36. TLEs for the mission are available from https://www.ariss.org/keps.html
Provisional elements for the upcoming Fram2Ham mission have also been added t0 the AMSAT TLE distributions courtesy of ARISS, and will be updated when the SpaceX Dragon vehicle attains orbit. Updates will be found at www.amsat.org/tle/dailytle.txt as appropriate. The mission has also been added to the AMSAT Satellite Status p[age for reports
Anyone may submit images to the gallery on the https://ariss-usa.org/ARISS_SSTV/submit.php page along with information about when and where the image was received.
Please note that because the Fram2Ham event is a competition, all submitted images will be held in a queue not available for viewing until after the competition judges have had a chance to make their decisions. After the winners have been announced, the Fram2Ham images will be available for viewing the same as all the other ISS SSTV campaign images. Teams and members of the general public are asked to *not* distribute copies of their received images to social media until after the winners of the competition have been announced.

GridMasterMap Satellite Top 100 Rovers April 2025 Rankings
The April 2025 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap on Twitter, has been released. The ranking is determined by the number of grids and DXCC entities activated, taking into account only those grids where a minimum number of QSOs logged on the gridmaster.fr website have been validated by a third party. Grid numbers do not directly reflect the exact number of activations. Satellite operators are encouraged to upload their LoTW satellite contacts to https://gridmaster.fr in order to provide more accurate data.

Changes to AMSAT TLE Distribution for March 28, 2025
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.
The following satellite has been removed from this week’s AMSAT TLE distribution:
KSU-Cubesat NORAD Cat ID 47954 Decayed from orbit on or about 21 March 2025
Provisional elements for the upcoming Fram2Ham mission have also been added courtesy of ARISS, and will be updated when the SpaceX Dragon vehicle attains orbit. Predictions based on these elements will be invalid if the launch is delayed past the planned 01 April 2025 03:20 UTC liftoff or if launch vehicle performance is off nominal. Updates will be found at www.amsat.org/tle/dailytle.txt as appropriate.

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.
The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.
Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.
The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html
The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html
